The Peculiar Features of the Foundations and the Artificial Bases Construction of the Covered Stadium in Cryolithozone

This paper describes how the erection of a covered stadium "Zapolyarnik" in Norilsk with a special internal microclimate on permafrost demands application of special actions for the preservation of the permafrost condition of the soils. The task for choosing an effective way of maintenance of stability of a field of stadium that will be used as a football field during the warm period of year as football and as an ice arena during the cold time is put and solved. The problem of maintenance of stability of the basis of a field and the stadium bases has the purpose — non-admission of the seasonal or long-term soils bases thawing through, including existing improperly sorted out soils of the powerful technogenic cushion fill. The exception of negative development unpredictable settlements - the bases soils blows up, capable to cause deformation the construction, is reached due to the transfer of the existing soils of the in bases into the stable permafrost state, including those which are close to the surface. Stable frozen condition of the soils of the bases of the football-ice field of the stadium is provided by the restriction of an unstable zone of the seasonal frost penetration - soils thawing through within the geotechnical system arranged on the existing surface and possessing with non-subsidence and non-blowup properties at the temperature changes, including a transition through 0°C. Quantitative forecasts are carried out by means of solving of a series of a task of non-stationary heat conductivity taking into account the mobile border of the phases separation (so-called Stephan condition). As a result of researches the temperature fields, peculiar for the soils of the bases during this or that period of time (the forecast is for about) are received at those or other types of influences through a surface. Simulation for seven various types of the arrangement of the artificial basis for the football-ice field is executed. The optimum multilayered construction arranged after maximum natural soils frost penetration of the basis is chosen. Temperature modes of a microclimate of a construction in winter and summer time of year are defined. The technical decision on the arrangement of the pile bases-covers for bearing arches of a covering of stadium is developed.
